I build the systems
behind good marketing.

I'm Sebastian, a marketing student at UCF who's spent the last two years managing real client campaigns. Somewhere along the way I got tired of doing the repetitive parts by hand, so I started building tools instead.

About

Marketer first.
Builder by necessity.

I'm a Marketing major at UCF, but honestly, most of what I know I picked up outside of class, running paid campaigns and funnels for small businesses that needed someone to just handle it.

At some point I got tired of doing the repetitive parts by hand. Reporting, intake, follow-up emails: the stuff that eats hours but doesn't need a person doing it. So I taught myself to automate it, and eventually started building small tools around the problems I kept running into.

That's the thread connecting everything here: campaigns that need a system behind them, and systems that need to actually move a number someone cares about.

Projects

Things I've
built and shipped.

01 / Legal Tech

Guardian Accountant

An AI-assisted accounting tool I built to help legal guardians manage the financial reporting courts require of them: the part of guardianship nobody signs up for, made a lot less painful.

Right now I'm working on getting Guardian Accountant adopted as the official guardianship accounting software for a Florida judicial circuit. Early days, but the conversations are real.
